LibWeb: Make Paintable::containing_block() return a PaintableBox*

Browse source 
Every single client of this function was immediately calling paintable()
on the result anyway, so there was no need to return a layout node!

This automatically leverages the cached containing block pointer we
already have in Paintable, which melts away a bunch of unnecessary
traversal in hit testing and painting. :^)
